Zero Configuration Philosophy - Ghostty is designed to work out of the box with no configuration for most users.

Optionally you can customize Ghostty via config file at ~/.config/ghostty/config

Extensions

Prompt

We will be using starship for prompt.

brew install starship
# after install, run:
echo 'eval "$(starship init zsh)"' >> ~/.zshrc

You can further configure Prompt by editing ~/.config/starship.toml. We provide Preset starship.toml with some cool icons and kubecontext enabled.

Usage:

starship explain # Explains the currently showing modules
starship module golang # Prints a specific prompt module
starship print-config # Prints the computed starship configuration

ls & ll

We will be replacing ls with eza Features: Colours, Grid view, Long view, Tree view, Git integration, Filtering and Icons Note: The icon characters must be present in the font you are using in your terminal

brew install eza

Usage:

eza --long --header --group --git

We also added following alias to our alias file, which is sourced from ~/.zshrc

alias ls='eza  --header --group --git --long'
alias ls.tree='eza --header --group --tree --level=2  --git --long --icons'

alias ll='eza --header --group --long --all'
alias ll.tree='eza --header --group --tree --level=2  --git --long --icons --all'

Shell Completions

We will be installing zsh-completions, zsh-autosuggestions and zsh-syntax-highlighting

brew install zsh-completions
# To opt-in to using completions for external commands
brew completions link
# You may also need to force rebuild `zcompdump`:
rm -f ~/.zcompdump; compinit
# Additionally, if you receive "zsh compinit: insecure directories" warnings when attempting to load these completions, you may need to run this:
chmod -R go-w $(brew --prefix)/share/zsh
compaudit | xargs chmod g-w
# install zsh-autosuggestions
brew install zsh-autosuggestions
source $(brew --prefix)/share/zsh-autosuggestions/zsh-autosuggestions.zsh
# install zsh-syntax-highlighting
brew install zsh-syntax-highlighting
source $(brew --prefix)/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
